Egg grading scale



Sept: 15, W36 G. w. LEKGHTON I EGG GRADING SCALE I I Filed Feb. 1, 1936PEEWEE SMALL MEDIUM LAR GE Patented Sept. 15, 1936 UNITED STATES PATENTOFFICE 1 Claim.

The invention relates to improvements in egggrading scales, in which acomputing device is arranged, dispensing with the handling of weights,and eliminating fluctuation of dial or indicator; and the objects of theimprovements are, first, to provide a dial that computes the differentsizes of eggs, corresponding to standard egg weights; second, to recordthe sizes of eg s instantly and accurately, by their respective names onthe dial; and third, to save time by eliminating the handling of weightsand fluctuation of dial or indicator.

I attain these objects by mechanism illustrated in the accompanyingdrawing, in which Figure l is a vertical section of part of the scale onthe line I, I, Fig. 3; Figure 2, a detailed view in perspective of thedial housing; and Figure 3, a plan View of the scale.

A tapered egg receptacle I is connected to balance beam 2, which isconnected by pin 3 to post 4; end of balance beam 2 is connected by pin3 to vertical rod 5, to which is attached weight 6 and dial I; circularform 8 supports disc weight 9 through which rod 5 slides, another discweight I0, through which 5 slides, rests on top of 8; the support forweight (5 and form 8 through which 5 passes, is H. Tubular housing I2,to which is attached cap I3, acts as guide to vertical rod 5. A plateI4, connects I2 and 4.

Encasing dial l, and attached to top of guide I3, is vertical housing I5(see Fig. 2) with horizontal slot where various sizes of eggs areindicated by their respective names, as per the following description:

When an egg weighing less than 1%, ounces is placed in I, it is not ofsufiicient weight to raise B and I, so it would indicate Peewee in theslot of I5, in Figure 2; an egg placed in I, weighing 1 ounces to lieounces will raise 6 up to 9, and dial I rises the same distance, andSmall would be indicated in slot of I5; when an eg weighing 1% ounces to1% ounces is placed in I, it causes 6 to lift 9 to I0, and dial I israised to indicate Medium in slot of I5; an egg weighing over 1 ouncesplaced in I, causes 6 to lift 9 and I5 to the guide I 3, and dial I israised to indicate 10 Large in slot of I5. When any size egg is removedfrom I, then 6, I, 9 and II] instantly fall back to original position,as per drawing (see Fig. 1).

The space between any two weights and the space between the top weightand the guide is 15 the same as the space occupied by each word on thedial.

I am aware that prior to my invention egggrading scales have been madewith various combination weights. I therefore do not claim such acombination broadly; but

I claim:

In an egg grading scale, the combination of a vertical sliding rod witha dial having names thereon attached at the top thereof, a weightattached to the vertical rod, disc weights having holes therein, throughwhich said rod passes, and supported on a form independent of said rodand spaced apart the same distance as the names on said dial; whereby,when an egg is placed on the scale, the diiierent weights are raisedfrom the form in accordance with the weight of the egg, thecorresponding name being indicated on the dial.
